Reflector Bead
Angles for R.I. = 1.54
56 facets + 16 facets on girdle = 72
4-fold, mirror-image symmetry
96 index
L/W = 1.000
P/W = 0.327 C/W = 0.327
H/W = (P+C)/W+0.02 = 0.674
P/H = 0.485 C/H = 0.485
Vol./W^3 = 0.225

Addition # 14 – This cuts fast and is fairly straight forward. Center the bead hole through C3 and P4 from point to point. This is designed to be cut in any semi-transparent to transparent material. I like it in Citrine and crystal quartz.
